After cutting its policy rate by 225 basis points in less than a year—from 5.00% to 2.75%—the Bank of Canada has shifted its focus from inflation control to supporting a slowing economy. Recent tariff tensions with the U.S. have further clouded the policy outlook, prompting the central bank to pause in April and June as it reassesses the balance of risks.
Despite this pause, a recent Reuters poll indicates economists expect at least two more rate reductions by year-end, potentially bringing the overnight rate to 2.25% or lower.
In this evolving environment, private mortgage investment portfolios face pressure from compressed yields, declining interest income, and shifts in borrower credit quality. In this article, we examine how these challenges can be proactively managed to preserve returns and ensure resilience through continued policy and economic uncertainty.
How Rate Cuts Impact Whole Loan Economics
Shifting monetary policy can significantly impact the economics of private mortgage investing. As the BoC’s policy rate decreases, yields on newly originated mortgages will over time follow suit, leading to shrinking interest payments for private mortgage investors. This compression in returns is further exacerbated by the potential for increased prepayment activity, as borrowers take advantage of lower rates to refinance existing loans.
This happens because borrowers are incentivized to refinance their mortgages in a declining rate environment, which can lead to accelerated prepayments, shortening the expected life of mortgage assets and reducing the total interest income investors receive.
While many mortgages, especially fixed-rate loans, carry prepayment penalties that can partly offset lost yield, the penalties are often insufficient to fully compensate for the reinvestment risk and the impact of shortened duration.
The other challenge for private mortgage investors is that credit spreads have remained historically tight despite weakening economic indicators, suggesting that the market has yet to fully price in rising credit risk. As a result, the risk-adjusted return profile is being compressed – investors may be taking on the same or greater credit risk for less incremental yield, potentially resulting in less attractive compensation for holding higher-risk loans.
Key Indicators to Monitor
Private mortgage investors can monitor several key indicators that directly influence risk, return and portfolio strategy. The Bank of Canada’s policy rate remains the key benchmark, influencing short-term interest rates and the broader yield curve, with four remaining announcements this year – in July, September, October and December.
Federal government bond yields, particularly the 5-year Government of Canada bond, serve as the primary benchmark for pricing fixed-rate mortgages, reflecting market expectations for interest rates over the medium term.
Additionally, tracking the lending rates of alternative lenders, commonly referred to as B-lenders, is essential. These lenders serve non-prime borrowers and typically offer higher-yield mortgages, making them a key segment for investors seeking enhanced returns.
Beyond rates, several economic indicators offer insight into borrower capacity and collateral strength:
- Shelter CPI gauges housing-related inflation, hinting at demand trends and the stability of real estate (collateral) values.
- Employment and wage data highlight borrowers’ repayment capacity, especially among non-traditional income groups common in private lending, and provide an indicator of potential arrears and default risks.
- Housing starts, building permits, and new listings provide early indicators of supply shifts that could pressure home prices and loan-to-value ratios.
- GDP growth and consumer confidence indicate broader economic health and housing demand trends.
- The Bank of Canada Credit Conditions Survey tracks lending standards, showing when tighter bank credit may drive more borrowers to private lenders, increasing deal flow but also increasing potential portfolio risk.
By actively monitoring these factors, investors and portfolio managers can anticipate market changes and adjust mortgage investment strategies proactively to manage risk and optimize returns.
Portfolio Adjustments: Balancing Yield with Risk
In a declining rate environment, the challenge of preserving yield must be balanced with sound risk management. Within a whole loan mortgage portfolio, this can be achieved through a combination of coupon laddering, selective exposure to second-position loans, and geographic diversification.
Coupon laddering involves holding a mix of mortgages with varying interest rates – maintaining exposure to older loans with above-market rates alongside newly originated mortgages with lower rates. This structure can help smooth cash flow over time and reduce reinvestment risk as older, higher-yielding mortgages mature.
Expanding into second position mortgages can offer incremental yield, especially as spreads tighten on first position loans. However, these strategies should only be pursued in alignment with an investor’s risk appetite, as they come with greater exposure to potential losses, particularly during periods of economic stress. Careful underwriting, conservative loan-to-value thresholds, and local market insight are essential when allocating to these segments.
Geographic diversification is another effective strategy. Shifting capital toward regions with stronger labour markets, stable housing fundamentals, and lower investor saturation can improve risk-adjusted returns and reduce vulnerability to localized economic downturns.
Regulatory Shifts
As rate cuts and economic data reshape return expectations, regulatory changes are also altering the lending landscape.
Canada’s banking regulator, the Office of the Superintendent of Financial Institutions (OSFI), is currently re-evaluating the mortgage stress test, a rule that requires uninsured borrowers to qualify at either 5.25% or their contract rate plus 200 basis points. Originally introduced to guard against rate shocks, the test is increasingly seen as misaligned with today’s lending environment. OSFI’s own research shows that it hasn’t meaningfully curtailed highly leveraged borrowing, with many households still taking on debt exceeding 450% of income, raising systemic risk concerns.
In early 2025, OSFI introduced a new loan-to-income (LTI) cap, restricting federally regulated lenders to issuing no more than 15% of new mortgages each quarter to borrowers above that 450% debt-to-income threshold. Now, the regulator is considering going further by scrapping the stress test altogether and shifting the focus from individual affordability to portfolio-level risk controls for lenders.
This shift, if adopted, could meaningfully reshape the competitive landscape. Traditional lenders may face tighter constraints on borrower qualification, while private lenders and MICs that operate with more flexibility could see an uptick in demand. But this flexibility comes with increased responsibility: lenders will need to ensure robust internal underwriting and risk management frameworks as the regulatory bar rises.
A final decision is expected after year-end, but any move in this direction could alter how mortgage credit is priced, approved, and risk-weighted, particularly in the private market where flexibility and discretion play a larger role than rigid ratios or stress tests.
Scenario Planning for 2025-2026
While macroeconomic conditions are notoriously difficult to forecast, economists have established a base case, bear case and bull case scenario for 2025-2026.
Base case: Gradual easing, slower growth
The BoC continues cutting rates to 2.25% by December as inflation eases within its target range and economic growth slows, but avoids falling into contraction or recession. In this environment, interest income declines modestly, while prepayment activity picks up only slightly.
In this environment, where prepayment activity increases only modestly, private mortgage investors can benefit from coupon laddering and selective second-position loan allocation to maintain cash flow.
Bear case: Trade shocks and recession risk
Escalating trade tensions with the U.S. trigger deeper economic weakness, pushing unemployment higher and straining household balance sheets. The BoC responds with accelerated rate cuts, potentially bringing the policy rate to 1.75% or lower. In this scenario, credit performance deteriorates, and prepayments slow sharply. The focus of private mortgage investment strategies shifts to capital preservation: lower-risk loans, tighter loan-to-value ratios, and regional diversification into provinces with more resilient job markets.
Bull scenario: Growth stabilizes, rates hold
If inflation stays contained and GDP growth surprises to the upside, the BoC may pause further easing and hold rates through 2026. Stronger housing turnover and improved borrower sentiment could lift origination volumes and prepayment activity. In this scenario, increased housing turnover and borrower demand may expand deal flow and create opportunities to capture wider yield spreads on newly originated loans, particularly in segments where borrowers are willing to pay a premium for speed or flexibility.
Across all scenarios, success depends on disciplined, risk-adjusted lending. Private mortgage portfolios built on rigorous underwriting and strong risk controls are best equipped to navigate uncertainty.
